is'intef osed in the test circuit for cutting out the att'eries thereof.

C designates'a local signaling cirouitin asuitable battery 0 and which is positioned a sounder or other suitable signaling device C. The local signaling circuit is normally closed by a pivoted circuit closer C which armature of the relay B in the test circuit.

screw 0 serves to hold. the armature normally away I from I its magnet and conse, quently close the circuit C, A hand switch in the signaling circuit C.-

D designates a terminal which is particu- A spring 'cwhich is provlded with -a suitable tension regulating c of any suitable construction is interposed larly'eificacious for locating crosses This terminal comprises a bow-shaped metallic to the extremities of which are ends of a flexible metallic ribbon-d In'use,

secured the on, owing to its flexibility, will contact with i a plurality of the segments thereof. Theleddescription herein-v lower portion of the handle d'of the terminal D which is formed of metal,-is provided with I I a transversely disposed aperture d? therein, I

which is adapted to-re'ceive one-of minals a of the test circuit A, said terminal being secured therein by a set screw or other the ter 5 While in the drawings I have shown only I a diagrammatic representation thereof aretobez'assembled in any referred manner and housed in the case whic may be readily transported from nals-a? are placed on segments side by side of 4 the commutator, as in Fig. 3, and the armature spring is adjusted so that when the terminals occupy this position the armature C will be attracted by its relay B holding the signaling circuit open. The terminals a parts place to place I for of the relay are conof my appa:

,ratus, it is of course obvious that the are then moved across the commutator and when the .short is located the relay will be short short test, the terminals D and a are shown in Fig. 0

moved around the commutator cross is located.

To test for 'a groun adjust relay so that it will attract its armature and openthe signaling circuit when the-test terminals 0. are placed on two of the commutator segments; then place one terminal a on shaft and until the .move the other around commutator, as

until signaling circuit is closed and sounder clicks.

To locate a particular coil on armature, adjust the armature spring so that when the test terminals are placed in two of the commutator bars, the relay will attract the armature, place one test terminal on one bar of commutator and run the other terminal around commutator and when the same con tacts thebar forming the other end of the coil, the-relay will be short circuited and its armature" will close the signaling circuit, therebv causing the sounder to click,

To ocate an o n adjust armature spring so that the re ay will just attract its armature when the test terminals are placed on two of the commutator segments, Test around commutator one segment after the other the sounder will click each time until ,the open is located when the armature will stand attracted by its relay and signaling circuit will be held open.

I claim: 1. In an armature test circuit a relay therein, a loca signaling circuit, a circuit closer therefor, said circuit 'multaneously contact with a plurality of testing ap aratus, a

closer constituting the armature of the relay iii the test circuit, a spring normally serving to hold said circuit closer in a closed position, and means for adjusting the tension of said sprin I 2. in an armature testing apparatus, a test circuit, a relay having a plurality of. windings thereon, means for cutting either of saidwindings into the test circuit, and signali v meanscontrolled by said relay.

3. 11 an armature testing apparatus, a test circuit, a relay having a plurality of windings thereon, means for cutting either of. said windings into the test circuit; a local signaling circuit, and means controlled by the relay in the test circuit for opening and cl.os ing the signaling circuit.

4. In an armature testing apparatus, a test circuit, a relay having a plurality of windings of varying resistance thereon, a switch for cutting either of said windings into the test circuit, a local signaling circuit, and means controlled by the relay in the test circuit for opening and closing said-local signaling circuit.

5. In an armature testing ap aratus, a test circuit, a relay having a pihralz'zty of windings 'of varying resistance thereon, a switch for cutting either of said wingiings into thetestcircuit, an armature for said relay, and a local signaling circuit adapted to be opened and closed by the movement of the relay armature.

6. A terminal for armature testing appa ratus having an elongated flexible contact face, whereby the same may be caused to sis commutator segments.

7. A terminal for armature testing a paratus comprising a bowed portion and a exible contact face extending thereacross.

In testimony whereof I have signed my 0 name to this specification in thepresence of two subscribing witnesses.
